Toall whomdtma monaern:

iiBe itglmown 7t tqL'RonnnNA. Gunn a citizen of the United- States,- and residing at Cincinnati, in |tl1e- :county :of Hamilton and State of Ohio, :have iinvented certain new andnusefululmprovements in Nalves with Donble Throw obwhiclnthe :Eollowing 1s, a. specification.

Luthe prior arta valve has lhad' -twoimotmns in the-:seine plane as inithel-qoetentito applicant #A1, lO1',9L-9,-June-3O,1914, Figures fiend 6* andrits specification; page 6 :column 2, parggzophfi; ibutthe .present invention :is the first! device to (uses valve sented overe P QMI 84 splane-simfwo and :having 'two 'di- ['BClllQIlSrDII manners-of motion to, and "from thessid surface and port.

IIn the drawings'Fig. 1-:is ;a :fronhiview of the new-valve motion. ,as, applied to rthe so called tempo-governor; :box of n .music player, the tempo :vzilve-ibeing mext to :the fulle t, degree of; opening, flflidnlthe special valve .seeted; Fig.2 Eis a similarviewi with the ,tempo valve fully :open andwthe especial valve tipped by. the thrust ;of.the tempo vatvepFigscfi end 4 are sectionsqat viewed irom theright end, showing thenor- 11ml end depressed conditionsvof themailer valve and the accelerator valve removed to allow view 'ofthe left; armof the rocker wiregnFigu 5 -;is, a view oft :the "accelerator valve seated, the dotted lines 1 indicating -,the some valvenvhenin its raised position Fig. fi-atplen view; of thetempomnditroiler valves at-the [full open position :of' the tempo valve as-im 2;; endFig, 7=-is a front view of thesnme. valves as in Fig. 2; nepeated ,for convenience of compelrison with plan-v-iew-of Fig. ;6,--and.hevingdotted lines; showing its reisedsposition [when .-the trailer valve is elevated by, the rocker wire.

The present improvement of two directions or manners of motion Of fl gVfllVG from itmsent is'lnow illustrated aswepplied to a tempo governor box of the. style shown in this annlicant s Potent ;:&-1;101-,626,June :30, 191-1, simply :as: one-employment ofthe present invention. but it is; toJoe understoood that the present :invention .is applicable to any purpose wherel-ardonble-control ofia valve is desired. end that theibroader claims henein aretintendedt-to cover an a plication OflillG novel valve motion herein set forth.

The particular dentures: of the tempo-govornorhox lltw t 'l. which he iprofic tinvon tion Specification of Letters Patent.

is1illustrated will :now be :first described; ifollowing which the special novel operation of the valve motion will beperticularized as exen'i-plified by the accelerator valve 313 of thesaid tempo-go'vernor-box.

=The tempovbox 1 shows a governor chamber2 lnwing a governor valve 3 for effecting an eventension air supply to the tempo ports 4 and 5.

The'governor pneumatic and spring and other customn-rv arts 015 a tension governing device are;notrshown,1but are understood to be'provided in any suitable manner, and might beat a distant :point, and vsoalso might the governor valve and chamber. T he present invention relatesto the quantity control of air: foridetermining =the speed of a wind motor-whichsoronels the music spools and sheet of a self-plaving musical instrument, which motor may be connected by conducting-means attached" to part6 .of the box 1.

Themort 7 is understood to be connected to the air tension (producing means, which is usimlly'bf varying tension. H of even tension, the connection mirrht be direct from such air tension producing moans to-thc tempo port 4.

A tempo valve 8 .has its position above tempo port/tend is movable from its closed position :oversaid port to an open position aSin Figs: 1 and'SZ. Such motion is efi'ected by, avnlveiwiret suitably connected to any manual control-means.

,-A nocleer 10 is of atlmil form hung on oentors atireer of its-end arms-and is connected by anarm 11 to any suitable manual control means adapted for effecting a secondary or nodi-f-ying control of tempo. To this rocker 10 are connected a trailer valve '12 and an accelerator vnlve13, and the tempo vnlve 8mm also be guided thereby. The guidance of the tempo-Valve 8Von rocker 10 is here shown as bv the valve 8 having a recess. or groove 14 lengthwisethereof, the front of said recess being closed by guards or clips 15. This groove 14 is of sufficient height to permit the rise of'rocker 10 when lifting trailer valve 12 and accelerator valve 13 and at the :same time retain the valve 8 in guidonce 1on-said rocker '10 the bottom of said groove 14 being suflicientl below the rocker 1fi-at normal nosition to allow the depression of the rocker when lowerirm trailer valve 12 heloW-normnlas shown in Fig, 4, The

trailer valve 12 is guided on rocker 10 by a ['OOX 16 1 I1"tl1 front of the valve 12 the rout of the grodve'being closed by guards 0r clips 17 and the height of the groove neatlv fitting rocker 10 so than the trailer valve 12 will always travel with said rocl: r r ltl fllhe trgiler v alve 12 is normally abort theseiitin whiehis the tempo port 4. as in Fi s. 1, 2 and 3, the arm 12? extended l'rum trailer valve 12 then keepin the rear edge of ithatfvalv'e l2 above/the seat, and this trailerwvalvei'l2 'is held against. the ri ht end of thetempo valve 8 by means 0' a spring '18 engaging both valves and pulling them together yet allowing an up and down motion-of the trailer valve 12 and raising ofthelaooelerator valve 13 by operation of the rocker 10 without disturbing the seating of the tempo valve 8. which is aided to its s'eat bya spring 19. When the valve 8 is moved bvaviie 9 and its manual control so as to open tempo port 4- as in Figs. 1 and 2. the downward operation of the rocker 10 swung on its centers b v arm 11 and its manua'lbontrol as in Fig. 4 will partly or wholly close whatever of tempo port 4 has been opened by tenipo valve 8 and its controlling connections, thus slowing or entirely stop ping the -motor from the speed set by the manual control of tempo valve 8.

The accelerator-valve 13 is guided at its front on rocker 10 by a groove 20 in the front of valve 13; the front of the groove 20 being closed by a guard or clip 21,"?15 shown in Figs. 1, 2 and 5, the top of said groove 20 being closely adjacent rocker 10 when latter is in normal position. and the bottom of said groove 20 being sufiicientlv below said rocker 10 when in normal position to allow the depression of the rocker when lowering trailer-valve 12. The one side of the accelerator valve 13 is guided against the. arm of the rocker 10 at left of said valve 13. and at the other side of said valve 13 by a guide-pin BZdriven into a solid'part of the box. The accelerator valve 13 lies normally closed over the accelerator port 5, but an upwardpperation of rocker 1.0 by arm 11 and its manual control will raise this acceL erator valve 13, as shown by dotted lines in Fig. :1, and allow air to flow through its port 5 to actuate the motor. either by port 5 alone if tempo valve 8 is closed over port 4. or to increase the motor speed set by the. tem 0 valve S'if that'is already open. Tn the latter case, the raising of the trailer valve 12 above its normal distance above port 4', as shown bvdott'ed lines of Fi 7, will free thatport 4 of some of the air rietion caused by its position over that port 4 and by that means also add to the speed of the motor.

The accelerator p'ort is'placed well to the rear of the accelerator valve 13. the same as shown in applicaiitsprior Patent #1,101,(l26,

so that the raising of its front end bv rocker 10 is greatly reduced in itsarnqnnt of motion over port 5, thus enabling a'very gradual and accurate control of the speed increase by lhis means.

The valve 13 has a screw or other suitable means 23 adapted to be contactedby .the tempo valve 8 just before the said valve 8 ieaches its fully open position as in Fig. 2, but to be clear of contact with said valveB when said valve 8 is at alessdegree of opening as in Fig. 1. i The said contact of the tempo valve 8 with the accelerator valve'13 causes the valve 13 to be tipped over and thus open the entire long edge of itsright side away from the seat 24 in which its related port 5 is located, thus'oausing a more free opening of the port 5 at such time than when the valve 13 is raised from its front end by the rocker 10 as herein before described. This sidewise raising of the valve 13 by the final part of the openin travel of the tempo valve 8 secures an ad ed service of air which the 'said final partofthe open ing travel of the tempo valve 8 will notac eomplish because of the obstruction by the trailer valve 12 of the air flow of the end of the port 4 last opened by'the opening travel of the tempo valve 8, but which is hooded over by the trailer valve 12 as will be seen from a study of these parts asshovvn in Fig. 1, assisted by the plan view Fig. 6, and the related front view detail Fig. 7.

It will'be seen that there is only a small height of opening under the front of the trailer valve 12, and still less under the rear edge. The ainount of air that can pass un der these two edges to the ort 4 is expressed by the curved lines 1 and Y in Fig. 6, the distance between line X and the front edge of the port 4 showing the amount of air flow under the front edge'of the valve 8, and the distance between the line 7 and the rear edge of the port tshowing the amount of air flow inderthe rear edge of valve 8, there being a dead part'Z'of the port 1, which is at the final part of the open-' in movement of thevalve S when there; quirement for the usual wind motor is io'r a greater increase of air flow'thanjior any other similar extent of movement of the valve 8 over port 51-. The previously described side tipping action of theaccelerator valve 13 at the'final opening movement of the tempo valve 8 over port 4; overcomes this lack of supply which has heretofore been a drawback in the perfect grading ojfthe speed of a tempo valve having a trailer as shown in the prior Patent. #1,101,626 and new improved as set forth herein."
